RuNPs stabilised by amino-decorated imidazolium-based polymer immobilized ionic liquids catalyse the dimethylamine borane mediated reduction of quinolines to 1,2-dihydroquinoline (DHQ) and 1,2,3,4-tetrahydroquinoline (THQ). Partial 3-substituted corresponding was achieved with 100% selectivity in toluene under mild conditions. This is first report selective partial 1,2-dihydroquinolines a heter...

Limited work has been conducted on trace metal(loid) exchange between sediment, water, feed, and shrimp, particularly in estuarine aquaculture environments. To identify sources the processes controlling bioaccumulation we analyzed paired shrimp samples collected Southwest Bangladesh late dry season (May), as well several common artificial feeds. Additionally, sediment extract from 24-hour labor...

Concentrations of Cu, Zn, Fe, Mn, Pb, Cd, As, and Hg were analyzed in the surface water muscle seven fish species (Carassius auratus, Cyprinus carpio, Hemiculter leucisculus, Pelteobagrus fulvidraco, Silurus meriaionalis, Ctenopharyngodon idellus, Parabramis pekinensis) from Wujiangdu reservoir, China. All metal concen-trations lower than grade one quality values. Mean concentrations decreased ...

Abstract Samples of raw waste water is taken from the municipal sewer Sumail district in Iraqi Kurdistan region and submitted to primary treatment by aeration evaluate their validity for irrigation potential health risks associated with this treated wastewater, Result revealed, (BOD) improved mechanical aeration, (COD) not enough bring it safe ranges. Ammonia NH 4 reduced 24 18 mg/L as converte...

Heavy metals have been widely researched around the world as a result of their deleterious and toxic effects on biotic ecosystems. On this premise, dearth ecotoxicological data regarding heavy metal (Pb, Cd, Zn Cu) content in African freshwater apple snail (Pila ovata) sourced directly from open markets Benin City, Nigeria warranted research. specimens mean weight 76.11±1.07 g were quantified b...

Background: We aimed to conduct a meta-analysis on the concentration of potentially harmful elements (PHEs) in carrots and potatoes irrigated by wastewater estimate non-carcinogenic health risks among adult children consumers. Methods: The risk PHEs concentration, including Pb, Cd, total Cr, Ni, Zn, Cu, Fe, edible parts carrot potato was investigated using random-effects model (REM). Accordingl...

This study was conducted to estimate the heavy metal pollution in groundwater, soil, fruits, and vegetables within cement industry its vicinity. Seven different fruits seven metals (Cd, Zn, Ni, Co, Cu, Cr, Mn) were selected for analysis fruit, vegetable samples by atomic absorption spectrometry (AAS). Results of this compared with National International Standards Pak NSWQD, WHO, USEPA. The pH s...

The samples of 4 mushroom species from the genus Leccinum ((Leccinum pseudoscabrum (Kallenb.) Šutara, scabrum (Bull.) Gray, duriusculum (Schulzer ex Kalchbr.) Singer, and albostipitatum den Bakker & Noordel) were picked 6 forested areas Slovakia in 2020 (Čačín – Jelšovec, Hliník Hronom, Kurima Taraš, Mníšek nad Popradom, Snina Štefekovo, Žákylské pleso). Total mercury content soil parts was...

The present study was conducted to evaluate the effect of traditional Bengal culinary practice on heavy metal content four carp species (Labeo rohita, Catla catla, Cirrhinus cirrhosus, and Hypophthalmichthys molitrix). Fish samples were collected from seven different farms located in Rajshahi district Bangladesh. processed cooked a currying method concentrations five metals (Pb, Co, Cr, Cd, Ni)...

Indexical appraisal of potentially toxic elements (PTEs) in sediment and fish riverine ecosystem give valuable information for environmental management. In this research, PTEs were measured soft tissues six species from an important breeding river (Halda) Bangladesh to assess quality human health risks. The abundance sediments varied the decreasing order Fe > K Ca Ti Zr Sr Rb Mn Zn Cu Ni Pb Co....
